LUBRICATOR.

No. 820,821. v

To all whont 'llt may concern Be itknown that l, JOHANNES TH. PannasEN,a citizen of the United States 0f America,

residing at Woodside, in the county of Queens,

city and State of New York, have invented an Improvement in Lubricators,of which the following is a specification.

My invention relates particularly to the class of f orce-feed orpower-actuated oil-feeding devices or lubricators especially adapted tosupplying lubricating-oil to the machinery ofmotor-vehicles,motor-boats, &c.; and the object of my invention is toprovidel a lubricator of simple construction and in which springs',check-valves, and other small and uncertain parts that are liable to getout of order are dispensedwith, and also to provide in the one structureavdevice which while I normally actuated by the power of the machinerybeing lubricated may also be manually operated, if desired, to supplyoil previous to starting up the machinery and without disturbing theconnections or devices for mechanically o erating the lubricator.

My improve lubricating device comprises,

" essentially, a revoluble shaft, a reciprocating tons in one positionthey draw the oil from the said sight-feed and in the other positionforce the said quantities of oil to the parts of the machinery to belubricated. The pistons of the series are moved longitudinally by arocker, which at the same time is actuated by an engaging revolublemember to reci rocate the series of pistons in ways provide therefor.These parts are contained in a receptacle holding the lubricating-oiland from .which the oil is drawn and forced to the sightfeed and fromwhich the oil received is forced to the machinery and parts beinglubricated.

The guides of the reciprocating series of pistons are provided withports at each side and the difference in length between the pistons andtheir cylinders and the diameter of the parts regulate the quantity ofoil moved Specification of Letters Patent. v

by each piston at each stroke.

Patented May 15,1906.

The sight-` 5 feed structure is provided with a regulatable oil-feedcontrolling the quantity of oill delivered to be forced to the machinery`and with means for returning the' surplus thereof to theoil-receptacle. devices and discharge-pipes agree with the number ofplaces to be lubricated.

In the drawings, Figure l is a vertical lon- The number of feed 6ogitudinal section and partial elevation of the devices of mylmprovement. Fig. 2 is a ver- 65 tical cross-section at right angles toFig. 1. Fig. 3 is a plan of the parts within the oil-receptacle with thecover broken o en and a horizontal section through the regu atableoilfeed devices, an end view of the slide, the 7o slotted rocker-shaft,and an elevation and partial section of the piston, together with asection of the slotted rocker-arm. Fig. 4 is /an elevation of theregulatable sight-feed device. through t e upper portion of thesight-feed. and through the regulating devices and in oppositepositions,the same being of exagj gerated size for clearnes's.` Fig. 7is an end elevation of the slide, showing the bearings 8o for theslotted rocker-shaft. Fig. 8 is a sectional end View of the slide, theslotted rockershaft, and an elevation and partial section of the piston,together with a sectiony of the slotted rocker-arm. Fig. 9 is a plan ofthe 85 v slotted rocker-arm. Fig. `10 is an elevation of thesame; andFig. 1l is a sectional plan at the dotted line :n shown in Figs. 1 and2.

Fi s. 5 and 6 are sectional plans 75 The receptacle for lubricatingmaterial is usually composed of the bottom a, back a', 9o

front a2, and ends a3, and formed therewith are lugs 4 for attaching thesame to a suitable support.

b represents the cover, preferably with a groove in the under surface,whereby the 95.

cover fits down over the upper edge of the body, the cover being heldtothe body by the screws 2 at the corners. one end is rovided with anaperture interiorly threa ed to receivethe filling-nozzle b', which isscrewed thereto, and the aperture o'f the nozzle is interiorly'threadedto receivey The cover at IOO the threaded plug or stopper b2, and Iprovide Y..

a sight-tube b3 at the front of the oil-receptacle to indicatethe levelof the oil therein.

c represents a shaft, and c a wheel or sprocket on the outer end of thesame, said shaft passing through a suitable bearingsleeve c2, secured,preferably, to the back a of the oil-receptacle and held in position bya nut 3 and provided with a packing 4. A belt or chain 5 passes aroundthe wheel or sprocket c for rotating Vthe shaft, power and movementbeing communicated by the mechanism that the device of my improvement isemployed to lubricate, and while I have shown in the drawings awheel andbelt it is obvious that a sprocket and chain may be employed in theirplace.

y On the inner end of the shaft c-that is, Within the oil vessel orreceptacle-there is a worm c3, and passing through the oil-receptaclevertically there is a shaft d. This shaft passes through the cover in anopening provided therein for the shaft, the bearing at the lower endbeing a bracket 8, secured as hereinafter described. Upon this verticalshaft d is a loose worm-wheel d', With which the worm c3 is in mesh.Around the vertical shaft d and secured thereto is a ratchet'dz, by itshub 6 above the ratchet, pinned to the shaft d, and the bearing-bracket8, coming below the loose worm-wheel d. These parts are held in positionon the shaft. Up'on this loose worm-wheel d there is a spring-held pawld3, mounted upon a stud 7, secured to the loose worm-wheel, the saidpawl b earing and meshing with the teeth of the ratchet d2.- At thelower end of the shaft d and secured thereto in any desired manner belowthe bracket-bearing 8 is a slotted crank-arm e.

I employ a frame secured within the oil receptacle or vessel and to thebottom thereof, which frame comprises the parallel side members ff andcross-connecting members f near the bottom of the vessel and coverplatesf2 upon the upper edges of the side members f and between whichcover-plates and the si e members are formed slideways for areciprocating frame of cylinders, hereinafter described. In these sidemembers f f are series of ports at predetermined places. (See especiallyFigs. 2 and 11.) In the lefthand side member f, Fig. 2, there are aseries of inlet-ports 9, four m number, agreein with the initialposition of pistons hereina ter described, and shown in Figs. 1, 2, and1 1, and through which ports 9 the oil from the reservoir enters. Inthis same side there are a series of intermediate ports 1( which riseand communicate with the pipes 11. These ports 10 are also four innumber. In the opposite or right-hand side member f, Fig. 2, there areseries of intake-ports 12 directly opposite the ports 9 and whichcommunicate with ipes 13, rising from the right-hand side memgerf, andthere are other ports, four in number, opposite to the ports 9 and whichmay be desi nated asdischarge-ports 14, which are in ine with pipes 15,that extend to the parts to be lubricated, and it is to be remarked thatwhile I have shown four series of port-s in each of the side membersthere may be any number of ports in the series, as the ports of theseries must in all cases agree in the lubricating device of myimprovement with the number of places to which the oil is forced forlubricating the machinery. The bracket 8,hereinbefore described, is tobe secured to or formed in one with the coverplate f2 at the right-handside for support.

g represents a reciprocating frame of cylinders, each of which cylindersis centrally and longitudinally slotted in the u per surface g', beingend bearings on the game g. This frame of cylinders is received betweenthe right and left hand side members f f and between surfaces preparedthereon and the under surfaces of the cover-plates f2. I provide arock-shaft h with trunnion ends in the bearings g, which rock-shaft islongitudinally slotted in the under surface, as appears from Figs. 1 and2. This rock-shaft has a pin h secured thereto and projecting from theupper surface. This pin passes through the slot of the crank-arm e andis advantageously provided with a roller (shown in Figs. 1 and 2)contacting with the inner surface of the slot of said crank-arm. Theslot in the said rock-shaft is indicated at 16. In the cylinders of thereciprocating frame g I place pistons i, which are shown as plaincylinders of metal each provided with a pin i', extending up through theslot of its cylinder and entering the slot 16 of the rock-shaft h.

The sight-feed devices for the oil and in which the movement thereof isvisually indicated are shown as extending above and attached to thecover b. This is for convenience and compactness; ,but it is obviousthat these sight-feed devices may be located anywhere in the line ofpipes conveying .the oil. These sight-feed devices are alike, andsimilar parts therein carry the same letter of reference, and thedescription of one will suffice for all. In each of these, c representsthe cylindrical glass section of the sight-feeding device, at the lowerend of which is a metal annulus 7c', secured in an aperture of the coverpreferably by overturning the lower edge and by the shoulder above thecover, while at the upper end there is an annulus k2.

In the lower part l represents a thimble centrally receiving the pipeA'13, the center of the thimble being made funnel shape for thedischarge of the oil into the pi e 13. At the upper end there is also athim le Z, which is o conical configuration centrally perforated. Thisthimble Z comes within the annulus k2 and extends above the same and issecurely held in position by the nut Z2, which screws upon the outersurface of the same down to the upper end of the annulus k2.

m represents a curved pipe the lower end of which passes into the pipe11, secured to the left hand of the side members f, Fig. 2, and theupper end of this curved pipe m passes up Within the sight-feed,`through the riorly and agrees in its taper with the conical interior ofthe thimble Z, and said valve'r is rovided with a central perforation 17and a ateral perforation 18 and with a circumferential by-pass 19, thecenter of which is in the same horizontal plane with the centerv of thelateral openingel. This particular construction is amply illustrated inFigs. 1, 5, and 6, and. the horizontal plan through the by-pass 19 andlateral opening 18 agrees with.

the upper ends of the pipes m and' n, which are made inclined, the upperend of the valve v1^ being provided With a kerf for a screw-driver,

by which the Same may be turned, or any other suitable mechanicalcontrivance may be employed for turning the said valve and indicatingits position.

In the operation of my improved liibricating device and after oil hasbeen filled into the vessel or receptacle the rotation of the shaft cand its worm @"irotates the worinwlieel rl and by its pawl di* theratchet Z2 and shaft d. The slotted crank-arm e turns with the shaft land by its rotary 'movement' actu- -ates the pin Zi and slottedrock-shafti to impart reciprocatingr movement to the pistons i oftheseries, all of the pistons moving simultaneously .in'the same direction.F rom the peculiar eonstruetionof this'l slotted crankarm c and itsrelation to the slotted roekshaft h and with s ecial reference to F 2and 3 it will be noticed that following the direction of rot-ationindicated by the arrow the further movement of said crank-arme cannotfurther swing the shaft Zz', because the same hasreached its extrememovement with thepistons. Consequentlythenexto eration will be to movethe reciprocating amel of cylinders g along in the slidewayr providedtherefor in the side members 1n this movement the piston-cylinders willgo from the series of ports 9 on one side to the series of ports 10 onthe same side and on the other side from the series of ports 14 to theseries of ports 1 2, (see Fig. 1 1,) and after reaching this positionthe further movement of the said crank-arm e will be above and over therockshaft Zz., swinging the saine fronrthe position shown in Fig. 2 toits opposite position and in so doing move the pistons i from theposition shown in Fig. 2 to their opposite position. In the movement ofthe reciprocating frame of cylinders and pistons from the positionsshown at the ports 9 to the position at the `pipe 13 to the ports 1()the oil drawn in at the ports Qwill be moved to the ports 10, and withthe swinging ofthe rock-shaft Zzy and the moving of the pistons to theop )osite position (shown` iii Fig. 2) the oil will e forced into theports '1"0 and pi es 11, and so into the pipes m and up into t icsight-feeds, passing'either partlyT through the lateral opening-18 andby-pass 19, as in Fig. 5, or entirely by the by-pass 19, as in Fig. 6,or, if thevalve r is soset, the. entire amount of oil Will ass -bv-theopenings 18 and 17 in the sighteed,"aiid soI b v the' o positie end o tere With the return movement of the reciprocating frame of cylinders andpistons which will take place with the further movement of the slottedcrank-shaft e on the opposite side of the position shownin Fig. 3,returning said parts to the osition shown in full lines, Fig. 3, afterwliic i the further movement of said slotted crank-shaft to its positionshown in Fig. 3 will swing the rock-shaft Zi, and move the pistons intothe positionH shown-in yfull lines, Fig. 2, in which the oil drawn fromthe sight-feed devices will be forced through the pipes 15to the partsof the machinery to be lubricated. It is apparent that in this operationif the valve 1" is in the osition Fig. 6 all of the oil raised throngthe pipe lm will go by the b v-pass and the )ipe n andy be returned tothe receptacle, an( it.y is also obvious, referring to Fig. 5, that apart ofthe oil will goby the bhv-pass 18 and pipe n' and return to thereceptacle, while the other part will go by the openings 18 17 throiighthe sight-feed into the pipe 13 to be forced for lubricating themachinery, and it will be also apparent that if the lateral opening 18is in line with the pipe n the entire quantity of oil raised will passby the openings 18 and to be forced to the machinery for lubricating.

I have shown in Fig. 3 the peripheriesof the nut Z2 and cap 0 askniirled, so that the saine mayl be grasped and turned by the iingers incase it is essential to separate the oilfeed devices and cover from theoil-receptacle and other parts, in which movement the thiinbles Z and Z,being firmly eonneeted'by the pipes m and 1i, come awa-y with said pipesand the pipe 1B, leaving the. annulus Z" alone secured to the cover,'and they may be replaced in the reverse manner. The movements hereindescribed are continuously repeated so long as the machinery tobelubricated is running, driving the belt or chain 5, and it is alsoobvious that Ythespeed at which ports tobe drawn into the: the pistonsand be retained .ICO
